BTW, shouldn't this work?
<hansl>
matrix m = {1, NA}
eval misszero(m[2])
</hansl>
I'm getting an error "is matrix not series", but m[2] should -I believe-
be auto-converted to scalar type here.
Actually no. The policy for some time now has been that a 1x1
submatrix remains a matrix in the course of calculation, and is
auto-converted to a scalar only on assignment. This seemed to be the
way to minimize unexpected results.
